Application filed July 16, 1917.

Z 0 all whom it may concern:

Be it known that I, l/VALTEP. L. IsoM, a citizen of the United States, residing at Crows Landing, in the county of Stanislaus, State of California, have invented certain new and useful Improvements in Mechanical Hay-Shockers; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the charactors of reference marked thereon, which form a part of this application.

This invention relates to improvements in the art of shocking hay in the fields and the aim of the invention is to produce a mechanically operated means for shocking the hay instead of forking the same manually as is now the common practice. The invention further designed to make as good, if not better, a shock than the manually formed one and deliver the same from the machine on the ground in an easy and efficient manner.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views. 7

Figure 1 is a side elevation of the complete machine.

Fig. 2 is a top plan View of the same.

Fig. 3 is a rear elevation thereof.

Referring now more particularly tothe characters of reference on the drawings I first provide a base frame 1 mounted on rear rollers 2 and front driving wheels 3. Projecting upwardly from the frame 1 is a vertical frame work 4 projecting outwardly from which is an auxiliary frame 5 mounted at its foremost endon a tiller wheel 6. On the frame 5 is the drivers seat 7 and the draft pole 8 projects from the front end of such frame 5. Mounted on the frame 1 and suitably constructed and supported by the frame work 4 is the shocking hopper 9, which is substantially cylindrical in shape and is provided at its upper end with a funnel shaped delivery chute 10. The hopper 9 is provided for a greater part of its circ mferente wi h two hing d doors 1:

ranged to be opened outwardly away from each other when the shock is to be delivered therefrom in the manner as will presently appear. An inclined platform 12 extends from a point at its upper end near the chute I 10 down to a point adjacent the ground where it is provided with a collecting fork 13. A projecting plate 14 is disposed along the under side of the fork 13 which prevents the hay from working through the fork 13 and back of the platform 12. An endless rake .15 is movable over the platform 12 and over the delivery chute 10. As the shocker is moved along the fork 13 collects the hay and the teeth 16 of the endless rake 15 engage the same and carry it up the platform 12 and deliver it into the chute 10. The fake 15 is suitably driven by means of a chain 17 mounted on a sprocket wheel 18 on the shaft 19 of one of the wheels 3 and extends likewise over a sprocket wheel 20 on the drive shaft 21 of the endless rake 15. A clutch 22 on the shaft 19 is used to place the wheel 18 in and out of driving relation with the said shaft 19. I

When the hopper 9 has received a sufficient amount of hay to make a shock the same isthen tamped and shaped ready for delivery from the hopper 9 by means of the following structure. Hinged within such hopper 9 to the inner circumference of the doors 11 are two tamping plates 23. Each plate 23 is provided with a pair of depending arms 24 and 25 projecting outwardly from the ends thereof through the sides of the doors 11. On the arms 25 are springs 26 which normally pull against such arms to hold the tamping plates 23 up against the sides of the doors 11. On the arms 24 are cables 27 which extend aroundsuitable pulleys and connect with a foot lever 28 pivoted adjacent the drivers seat 7. When the hay is ready to be tamped within the hopper the driver presses against the'foot lever 28 which action through the medium of the cables 27 pulls on the arms 24 and presses the plates 23 down against the hay tamping it and rounding it out into proper shape for a shock.

This tamping operation being completed it is then necessary that the shock be delivered from the hopper 9 onto the ground and this I accomplish as follows: The bottom of the hopper 9 is open. and the hay when filled into the hopper piles up upon m 2 xtend g a res th bo t m of such hopper 9. This draper is movable over rollers 30 and extends to a point at the end of the machine and is driven by means of a sprocket wheel 31 connected by a chain 32 with a sprocket wheel 33 fixed on a pinion 33 meshing with a pinion 33 mounted on the shaft 19. The pinion 33 is arranged to be placed into driving relation with such shaft 19 by a clutch 34. throwing the clutch in and out of driving relation with such pinion 33 will be explained hereafter.

The doors 11 are provided with projecting arms 35 one on each door. One of the arms 35 connects with one end of a vertical lever 36 and the other arm connects with the opposite end of such lever 36. V

' A rod 37 connects with the lever 36 and to a bell-crank 38. A. link 39 connects from the bell-crank 38 to another bell-crank 40. From this bell-crank 40 another link 41 connects with a bell-crank 42 connected with p a lever located adjacent the seat 7. This v Copies of this pat ent may be obtained for five cents each, by addressing the Commissioner qt Patents,

lever 43 operable over a quadrant 44 having three fixed notches 45, 46 and 47 respectively. When the lever is set in the notch 45 the doors 11 are closed and the clutch 34 is out of engagement with the gear 33. A bell-crank 43v is also connected with the lever 43 and by a link 49 is likewise connected to another lever 50 provided with a pair of shifting arms 51, one leading to the clutch 22 and the other to the clutch 34. When the hopper 9 is full of hay and ready to be tamped into shape the lever 43 is pulled to the notch 46. This disengages the clutch 22 from the. sprocket wheel 18 and thereupon the delivery of the hay into the hopper 9 ceases. The operator thenpresses upon the foot lever 28 and tamps the hay into shape in the manner already described. Then the lever 43 is moved back to the notch 47 This action through the bell-crank and the link mechanism described drives the lever 36 so as to pull on the two arms 35 in opposite directions with respect to each other, which action opens the doors 11 in opposite directions. Immediately following this operation the movement of the lever 43 moves the lever 50 so as to throw the clutch 34 into engagement with the pinion 33'. This action causes the shaft 19 to drive the draper 29 at a speed substantially equal to the speed with which the entire device is moving and hence deposits the shock gradually upon the ground so as to cause it to hold its shape and remain intact. This be-' The means of ing done the movement of the lever 43 is reversed and this closes the doors 11 and disconnects the clutch 34 from the sprocket wheel 33 and throw the clutch 22 into engagement with the sprocket Wheel 18 whereupon the delivery of the hay into the hopper 9 is resumed. V

Fromthis description it will be apparent that the hay can be picked up, shocked and delivered bv the mechanical means here described and deposited on the ground in a very rapid and etficient manner, thus completely doing away with the necessity of manually handling the hay.

From the foregoing description it will be readilv seen that I have produced such a de. vice as substantially fulfils the object of the invention as set forth herein.

v \Vhile this specification sets forth in detail the present and preferred construction ofthe device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention as defined by the appended claims.

Having thus described my invention what I claim as new and useful andv desire'to secure by Letters Patent is:

1. A mechanical hay shocker comprising in combination a hopper, delivering means discharging into the hopper, tamping members within the hopper, hinged doors on the hopper, a draper forming the bottom of the hopper, and means whereby the delivery means may be stopped, the tamping members operated, the doors opened and the draper started in motion in the order named.

2. A mechanical hay shocker comprising a hopper, hinged doors on the hopper, a

draper forming the bottom of the hopper,

a delivering means discharging into the hopper, a single lever operable to place the delivery mechanism in or out of operation; to open the doors when the delivery mechanism is inactive; and toy place the draper in operation when the doors are open.

' 3. A mechanical hay shocker comprising a hopper, tamping members within the hopper, a crank on each end of each member projecting outside the hopper, springs con-. nected with one pair of cranks to. normally hold the tamping members away from the cross sectional area of the hopper, and pull cables connected with the other cranks to drive the members downwardly to. tamp the material in the hopper.

In testimony whereof I aflix my signature.
